MEP / Building Systems

HVAC / Mechanical Engineering

Mechanical engineering for heating, cooling, ventilation and related building equipment.

What this covers

Understanding HVAC / Mechanical Engineering

Mechanical design considers the space, its use and the conditions the system needs to maintain. Share a layout, occupancy information and equipment data to help the engineer define capacity and distribution, and coordinate with other trades.

When engineering may be required

When to involve an engineer

An engineer may be needed when changing a building's use, modifying air distribution, replacing equipment with a different design or preparing mechanical plans.

Confirm the engineering scope with the professional you engage and any permit requirements with the local building department.

Engineering tasks

What the engineer may review

Topics that may be relevant to the review: air handler, chiller and condensing unit.

The engineer can review existing conditions, evaluate the proposed changes and prepare the calculations or design details included in the agreed scope.
